1. Cut various colors of ribbon into small pieces, about 3-4 inches long. The thickness of your ribbon and the size of your craft foam cone will determine how many pieces you will need to cut in order to complete the tree.
2. Take one piece of ribbon and fold it in half creating a loop; pushing a T-pin through the two loose ends of the ribbon, pin it to the craft foam cone. It's best to start at base of the cone, placing each ribbon loop next to the previous one, and working your way up. Use different ribbon colors to create the pattern of your choice. Be sure to hide the pins in lower rows with the ribbon loops from the row above.
3. Wrap a piece of ribbon around top of the cone to hide the top row ribbon's edges. Secure with a pin.
4. Glue a bow to the top of the tree as the finishing touch!
